mobi Cover does not appear
I just started using calibre on a Macbook Pro, OS X Lion 10.7.4. Everything works fine, except that when I add a cover jpeg it does not appear in the viewer when I generate a .mobi file. And of course the cove does not appear when I upload the book to my Kindle 3.3. The cover does appear when I generate an ePub file.
I am using all default settings, out of the box. I have not changed any settings in Preferences.
